  1. Huge knock issue.

    Everything you’re saying makes sense but oddly enough ...now that I’m on e85 at a much higher power level, my head temps drop almost 20 degrees after a WOT pull. That never happened on 91 at almost 200hp less. Is that not due to the fuel change? ive been wanting to change my coolant ratio for a...

    Nothing crazy....274/40/19 ps4s’s
  3. Procharger intake! I need your honest feedback

    Power wise, I think you’d be better off just making the inlet diameter smaller in order to get down to cooler air...
  4. Anyone on e85 full time: upper lube?

    Anyone on e85 consistently using any upper lube? ... any particular ones you recommend? I’m thinking I’ll try the power plus stuff...
  5. Supercharger Gearing

    I’m running 3.73 with about 750whp and for having fun around town nothing can beat it. 1 and second can get scary but if you’re cruising and need to “pass” somebody lol...3rd is about as good as it gets for a 45mph start.
  6. Huge knock issue.

    is this head cooling flaw still an issue if running e85? I was thinking of also adding a water meth kit with perhaps a slight emphasis on the water to help with egt’s. I would think that would be more than enough to control cylinder temps without having to mess around with coolant flow. Thoughts??
  7. VP racing M2 upper lube safe for cats??

    I know it’s not as simple as my question but just humor me haha... Since you have some serious chemistry knowledge would you mind looking at this SDS? Looks to me like it would be o2 and cat safe...
  8. Cooling Mod?

    If there is no way to confirm lower temps on cylinder seven and eight after the mod how are people confirming that it actually is working. Just simply that 7 and 8 aren’t burning up?
  9. VP racing M2 upper lube safe for cats??

    Gotcha, that makes sense.. I’m probably somewhere in between.. I don’t really race the car but I’m running e85 full time so I’m looking for anything that decrease wear and increase longevity. I talked with VPs phone tech which wasn’t really helpful...he said it should be fine because there are...
  10. VP racing M2 upper lube safe for cats??

    Wow... there’s that knowledge drop I was looking for! Haha Thanks so much for all the helpful info! So no real concern for cats it would seem. Would you think plugs/sensor fouling is that likely? what do you think about this? A better/safer alternative...
  11. VP racing M2 upper lube safe for cats??

    Hi there, I'm curious if anyone could give me info on VP's M2 upper lube for alcohol fuels. Does anyone know if it is cat/O2 sensor safe? Pretty simple composition: Barium bis(dinonylnaphthalenesulphonate) - 1%-10% Methyloxirane homopolymer - 90%-99% Anyone have any petrochem knowledge they'd...
  12. P0030 code which sensor to check? Help!

    that’s a good idea... can you confirm that p0030 is in fact bank one?
  13. P0030 code which sensor to check? Help!

    Hey so I threw a p0030 code the other day. O2 Heater circuit failure. Cleared it and checked for 12v to sensors. All seems well but it threw the light again. So I’m pretty confident i need to replace a o2 sensor. Question is: which one? Anyone run into this problem? How am I able to determine...

    I would love to know more about this What is his thinking on using marvel mystery oil? What specific parts are of concern regarding lubrication ?

    I would love to see an advanced tech section as well!!
  17. Turbo Owners Running Cats - Which Brand Holds Up?

    That’s the rule I live by;) haha Yeah obviously that’s true... I was gonna add the caveat that of course I break the law but $800 bucks for peace of mind every time I’m pulled over and every time I have to get emissions tested. . .It just felt like it was worth it. Blasting through 3rd on a...
  18. Turbo Owners Running Cats - Which Brand Holds Up?

    For me I decided to go with cats for two reasons mainly. First, the noise. With just a catback, the car was already a little too loud/droning for me, so I knew that adding lth’s and taking out cats was gonna be way too much. And second, no judgment on anyone else at all but for me...
  19. Turbo Owners Running Cats - Which Brand Holds Up?

    Here’s what I’ve come to learn: There are rare circumstances or post ignition that can blow up cats but for the most part it’s quite the opposite. The leaner the mixture the hotter the egt =cat failure. And in fact, the ecu will begin adding more fuel if the cat temps start getting out of...
